Question

Show transcribed image textIn the primitive machine shown in Fig. P6-3, the air-gap flux density Bs has a sinusoidal distribution given by Bs = Bcos theta. The rotor length is l. (a) Given that the rotor is rotated at a speed of omega m, plot as a function of 0 the emf e11, induced and the torque Tem acting on the coil if Ia = I. (b) In the position shown, the current Ia in the coil equals I. Calculate Pet, the electrical power input to the machine, and Pmech, the mechanical power output of the machine, if omega m = 60 rad/s.
